Avoltmeter has an internal resistance of 10 000 ω and is used to measure the voltage across a 47.0-ω resistor that, without the voltmeter connected, has a current of 1.20 a pass through it. how much current is drawn away from the circuit by the voltmeter when it is connected across the resistor? 1) 4.7 ma 2) 5.6 ma 3) 1.205 a 4) 0 a

Trumpeter a holds a b-flat note on the trumpet for a long time. person c is running towards the trumpeter at a constant velocity. person b is running away from the trumpeter at the same rate. person d is standing still the whole time. which person hears a frequency that is lower than the b-flat?

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?
